1 Claim. (on. 20-53) My invention relates to new and useful improvements in windowconstruction'.

An important object of my invention is to provide a window construction having inner and outer panels, each comprising a plurality of sections maintained in spaced parallelism to provide a dead air space therebetween, and wherein the air space will effectively insulate the inner panel from outside inclement weather conditions.

Another object of my invention is to provide a window construction of the above-mentioned character wherein the dead air space between the panels will permit the air within the building to warm the inner panel to prevent sweating of the said inner panel caused by condensation of warm, moist air on a cold pane of glass.

Still another object of my invention is the provision of a window construction of the abovementioned character wherein one section of both the inner and outer panels is hingedly mounted to permit opening of the same for ventilation purposes and wherein a unique fastening means is provided for the said hinged sections to permit both the inner and outer sections to be latched from within the building and the inner panel to be opened independently of the outer panel.

Yet another object of my invention is the provision of a window construction of the abovementioned character wherein certain of the panels are adapted to be constructed of glass panes for winter use and to comprise a suitable wire mesh for use during warm weather.

Other objects and advantages of the invention will be apparent during the course of the following description.

Figure 10 is ,an exploded perspective view of the plunger and sleeve, and

Figure 11 is a fragmentary front elevation 11- lustrating the glass swinging panel of Figure 1 replaced by a swinging panel covered by asuitable wire mesh.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention,the numeral I 0 designates a casement or frame here illustrated as being substantially square in front elevation and having top and bottom rails II and Hand stiles I3 and It. The numeral l5 designates the outer face of the casement and the numeral l6 designates the inner face thereof. The casement I0 is transversely divided by a bar I! disposed in spaced parallel relation with the top and bottom rails II and I2 and substantially three-fourths the height of the casementfromthe bottom rail [2. The bars 18 and I 9 are equi-spaced from each other and from the stiles l3 and M of the easement and further subdivide the casement into horizontally spaced congruent openings. The bar I! is of substantially the same thickness as the stiles for its entire length, and the portions 2D'and 2| of the bars 3 and I9 extending between the bar' I! and bot-- tom rail I2 are of substantially the same thickness as the stile and rail, while the portions 22 and 23 extending between the bar I1 and the top rail l I extend flush with the outer face 15 of the casement but are of substantially reduced thickness.

The bars l1, l8 and I9 divide the frame l0.

into panel-receiving openings 24, 25, 26 and 21. The opening 24 is bounded by the stile l3, bars I! and I8 and bottom rail l2; the opening 25 is bounded by bars l1, l8 and I9 and the bottom rail l2; the opening 26 is bounded by the bars I! and I9, stile l4 and bottom rail l2; the opening 21 is bounded by the bar |1,-stiles I3 and I4 and top rail I I; and the upper portions 22 and 23 of the bars "3 and [9 further subdivide the outer face of the opening 21 into horizontally spaced congruent openings 28, 29 and 30.

The opening 24' is further subdivided into a plurality of vertically spaced congruent openings 3|, 32 and 33 by the horizontal lattice strips 34 and 35. The lattice strips 34 and 35 extend between the stile l3 and the lower portion 20 of the bar I8, is flush with the outer face l5 thereof,

and is of substantially reduced thickness. The opening 25 is similarly subdivided into a plurality of vertically spaced congruent openings 39, 31 and 39 by the lattice bars 39 and 49. The lattice bars 39 and 49 extend between the lower portion 2I of the bar I9 and the stile I4, are flush with the outer face of the bar and stile, and are of substantially reduced thickness. The peripheries of the openings 29, 29, 39, 3|, 32, 33, 39, 31 and 39 thus formed in the easement I9 are formed with outwardly .clirected rabbets to receive the panes of glass H, which panes may be secured therein by strips of putty 42, or the like.

The periphery of the opening 21 at the inner face of the casement I9 is rabbeted to receive the elongated panel 43. The panel 43 comprises top and bottom rails 44 and 45 maintained in spaced parallel relation by the stiles 49' and 41, and the enclosure thus formed is further subdivided into horizontally spaced congruent openings 48, 49 and 59 by the vertically disposed bars SI and 52, the peripheries of which openings are rabbeted to receive the panes of glass 4|.

The upper edge of the top rail 44 of the panel 43 is formed with a longitudinally extending tongue which is adapted to be received within the groove 52 formed in the bottom edge of the top rail I I of the easement to hold the panel fiush with the inner'face I9 thereof. The bottom rail 45 of the panel is provided at spaced intervals therealong with vertical bores 53 which align with the cul-de-sacs 54 formed in the upper face of the horizontal bar I1. Latch assemblies 19 are disposed within the bores 53 in a manner to detachably seat within the cul-de-sacs. Each of the assemblies includes a sleeve 55 immovably received by a bore 53 and formed at the end 51 thereof with a plurality of spaced longitudinal slots 59 to define the resilient finger elements 59. A cylindrical plunger 58 is adapted to be slidably received within the sleeve 55 and is formed adjacent the end 99 thereof with a tapering throat portion 6| whereby the plunger may extend through the sleeve and into the culde-sac 54. The resiliency of the finger portions 58 of the sleeve will permit the same to spread when the end 99 of the plunger is received by the cul-de-sac 54 and retraction of the plunger from the cul-de-sac may be easily eflected. The removal of the plungers from the bore 53 however is prevented by the finger elements 59 which slidably contact the throat portion 6| of the plunger and abuttingly engage the offset portion 92 of the end 89.

The peripheries of the congruent openings 24 and 29 are rabbeted at the juncture thereof with the inner face I8 of the casement to receive the panels 93 and 94. The panels are formed with top and bottom rails 95 and 99 maintained in spaced parallel relation by the stiles 91 and 98 and the opening defined thereby is subdivided by horizontally disposed lattice bars 99 and 19 into vertically spaced congruent openings 1|, 12 and 13, the peripheries of which are rabbeted to receive the panes of glass 4|. The outer stiles 91 of the panels 63 and 94 are formed with longitudinally extending tongues 14 which are received by aligning grooves in the inner edges of the stiles I3 and I4 of the casement I9. The inner stiles 99 of the panels 63 and 94 are provided with latch assemblies 19 which cooperate with aligning cul-deesacs formed in the bars I8 and I9 in the same manner described for the top panel 43.

The opening of the easement is formed with a central peripheral bead 11 which defines outer and inner rabbets 18 and 19 adapted to receive the outer and inner swinging panels 99 and 8|, respectively. The swinging panels are formed with horizontally disposed top and bottom rails 82 and 83 maintained in spaced parallel relation by the stiles 94 and 85 and the opening thus defined is subdivided into vertically spaced congruent openings 89, 81 and 89 by the lattice bars 89 and 99, the peripheries of which last-mentioned openings are rabbeted to fixedly receive the panes of glass H. The stiles 94 of the inner and outer swinging panels 8i and 99 are connected to the vertical bar I8 in the casement by the hinge members 9|, whereby the stiles may swing outwardly of the said casement.

A keeper 92 is embedded in the rabbeted edge 19 of the vertical bar I9 and fixedly maintained therein by the screw members 93. The keeper is formed with an opening 94 which registers with the'recess 95 in the bar I9. A hasp 99 is hingedly secured to the inner face 91 of the outer swinging panel 99 by the screw members 99. The pivoted bar 99 of the hasp is bent to extend around the bead 11, against which the panel 89 abuts when in the closed position, and to extend in superposed relation to the keeper 92. The extending end I99 of the baris then disposed at right angles thereto to define a finger piece adapted to frictionally engage the inner face of the bar I9 in a manner to hold the panel 99 in the closed position; The pivoted bar 99 is provided with an opening I9I which registers with the opening 94 in the keeper in a manner to permit the spring-pressed plunger I 92 of the latch I93 to be received by the keeper. The latch I93 is mounted on the inner face of the panel M and includes a knob I94 which extends through the slot I95 in the latch casing. The inner end of the knob is attached to the plunger I92 in a manner to slidably operate within the slot I95 and to provide a means whereby the plunger may be slidably actuated into and out of engagement with the keeper.

As illustrated in Figure 11, the openings in the hinged panels may be closed either by glass or a suitable wire mesh. During the warm summer months it may be desirable to replace the glass panel 99 with a screen panel I99. The panel I98 is similarly provided with a hasp 99 which cooperates with the keeper and latch I93 of the inner panel in the same manner described for the swinging panel 89.

The casement I9 is adapted to be permanently mounted in the window opening of a building and the unique construction of the same provides adequate protection against inclement weather conditions during the cold weather months and permits ventilation during the warm summer months.

It may be seen that the outer openings 28, 29, 39, 3I, 32, 33, 36, 31 and 39 of the casement have panes of glass 4I immovably positioned therein and that the inner openings 24, 29 and 21 receive removable panels 43, 53, and 94. By virtue of the unique construction of the removable panels and the manner in which the same are fitted within the receptive openings, they may be easily and expeditiously removed-to permit cleaning of the inner surface of the fixed outer panes of glass. When inserted in the manner hereinbefore described, the removable panels will be securely held against casual displacement relative to the easement and provide a dead air space between the inner and outer panes H which effectively insulates the inner panes from the outside air. The dead air space permits the inner panes to assume the same temperature as the air within the building thereby preventing condensation of the moist, warm air within the building on the said panes. The air space is also advantageously employed to prevent escape of the warm air within the building, either through or about the casement, thus efiecting a substantial saving in the heating of the building.

The unique construction and mutual cooperation of the hasp 96 carried by the outer swinging panel 80 and the latch I03 carried'by the inner swinging panel 8| permits both of the panels to be easily and expeditiously locked from within the building. This unique construction and association also permits the inner swinging panel 8| to be opened independently of the outer panel. This coaction is particularly advantageous when the outer panel 80 is replaced by the screen panel I08 whereby opening of the inner panel I03 will provide adequate ventilation through the screen panel. By providing the means for fastening the outer panel from the inside opening of the same by a person outside the building is eflicaciously prevented. The unique manner in which the swinging panels are associated with the frame in no manner destroys or diminishes the beneficial results obtained by the dead air space therebetween. I

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same and that various changes and modifications in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the appended claim.

What I claim is:'

'In a window construction having a frame and spacedparallel panels hingedly associated with the frame, the improvements comprising a keeper carried by the frame, a latch carried by the swinging end of one of the panels and extending intermediate the frame and the other of the panels, said latch having an opening adapted to register with the said keeper, an oiIset end portion adapted to i'rictionally engage the frame, and asliding latch element carried by the second panel, said latch being adapted to extend through the opening in the first latch and to be received
